Step-by-step explanation:
12 x 2/3= a. a being his current age. hope this is correct!
Simplify the following:
sqrt(5) - 16 + sqrt(15) - 8
Grouping like terms, sqrt(5) - 16 + sqrt(15) - 8 = sqrt(15) + sqrt(5) + (-16 - 8):
sqrt(15) + sqrt(5) + (-16 - 8)
-16 - 8 = -24:
Answer: sqrt(15) + sqrt(5) + -24
Answer:
Step-by-step explanation:
So we have the expression:
FOIL:
Simplify:
Recall that i² is just -1. Thus:
Simplify:
Combine like terms:
Add:
And we're done!
